-# note ELOOP limit used to be 32 but changed to 8. Who know what
-# it might be next.
-#
+# Note1: On Linux, ELOOP limit used to be 32 but changed to 8, and lately
+# its become 5. Who knows what it might be next.
+# Note2: On IRIX, the limit is around the 30 mark.
+#
+# What we are looking for here is: no panic due to blowing the stack;
+# and that the ELOOP error code is returned at some point (the actual
+# limit point is unimportant, just checking that we do hit it).
